Nothing really changes. Although many times, there is a humorous conversation. Example:When you're with Omid about to jump onto the trainLee-...Omid-Fuckin' scary, right?!*looks back at oncoming herd*Omid-Scarier *pushes Lee onto the train*

Sometimes being silent is actually better. If you remain silent in the middle of Carley's reasoning for speaking about your past in episode 3, she gives an entirely different speech about it, which i think is better than her other one.

most of the time being silent is negative. Like between all the arguments of different groupmembers (lilly vs kenny, kenny vs christa etc etc) BOTH will hate you for not siding with someone instead of just one. Silent option is only viable in extremely few scenarios.

If you don't say anything when you're having that (one-sided, in this case) conversation with Carley on the balcony of the motor inn, she'll kiss you on the cheek and say "You're going to have to be more talkative if we're going to make this work."
